After scouting, participants dived into dataset of their particular interest.

Here are three examples of notable activities.

NYC Graffitti

New York City has a system in place to track Graffiti locations, this information is crowdsourced via phone calls to the 311 number. If you are walking around New York City and see a Graffiti that you would prefer to be removed, you can call this number and enter the graffiti in that database. On the other hand, if you have an appreciation for the Art of Graffiti, or are interested in their use for social and political expression, then you also have right there a Tourist guide for places where you will find graffitis to see (that is, until the City removes them…).

DJ. Deo and Alex Jurkat went after this dataset, downloaded it and massaged it, and developed a web application to display the locations of graffiti in a map. Given that the dataset includes dates information, their Web application also provides a slider to see the times when the graffiti appeared, and when they were removed.

…this led to a discussion on the merits of the Dalek’s invasion planning strategies…

With activities happening in more than 100 Cities around the World,
The Open Data Day Hackathon was a true celebration of what can be achieved
when Data is made available in usable forms for all to access.
